@mea: euphonix declined to work with us. I don't think it was malicious - they were supposed to get me technical specs etc. a couple of years. They never did, people at the company moved on, and they lost interest. If you want Ardour to support EuCon, you need to tell them that we're entirely willing to work with them but we need technical specs that we can use for an open source implementation.

Yes but you can use the Euphonix in Mackie mode, as evidenced by others in this thread. Obviously not going to argue about EuCon support though, and that seems even less likely now that Digi/Avid owns them.
